SPECIFICATION forming part of Letters Fatent No. 340,415, dated April 20, 1886.

V Application filed September 24. 1885. Serial No.177,977. (No model.)

To all whom, it may concern:

Beit known that I, WrLsoN BROWN, a citizen of the United States, residing at York, in the county of York, State of Pennsylvania, have invented a new and useful Improvement in Railroad-Rail-Joint Ohairs,which improvement is fully set forth in the following specification and accompanying drawings,in which- Figure 1 represents a top or plan view of a railroad-joint chair embodying my invention.

Fig. 2 represents a vertical section thereof in line 00 :0, Fig. 1. i Fig. 3 represents a vertical section of a modification.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a chair for the joint of railroad-rails, the construction and advantages thereof being hereinafter fully set forth.

Referring to the drawings, A represents a chair for the joints of railroad-rails,- the same consisting of the base B and checks 0 O, with the securing and tightening bolts D D it being noticed that the bolts D are vertical and the bolts D horizontal, as shown in Figs. 1 and 2.

- E represents splice-pieces, which are of angular form, the flanges or base portions E whereof embrace the base of the rail, and are extended laterally, so as to rest on the base B of the chair, the bolts D passing through the vertical portion E of the splice-piece and the web of the rail, it being noticed that the base is of width somewhat greater than that of the base of the rail and base port-ions ofthesplicepieces E, and the cheeks 00 rise from the base B, so as to embrace the base portions of the splice-pieces. The check Gis'integral with the base B, and the check 0 separate therefrom and secured thereto by the bolts D, which are passed through the cheek and base and tightened by the nuts D of said bolts.

It will be seen that the chair may be readily fitted in position and secured by the bolts and nuts, and by its use the strength of the joint is materially increased at its weakest point without making it rigid, while the base of the rail is kept on a common plane, reducing the possibility of lost motion and breakage of the splice. The tightening of the bolts on the cheeks counteracts the tightening of the bolts in the splice proper, and the cheeks being supported by the flanges or base portions of the angle-splice holds thelatter down, whereby a vertical support is given to the heads of the rails, instead of an angular support, as the tightening of theangle-splice bolts has a tendency to do. It will also be seen that the angle-splice pieces are subject to the adjusting actions of the bolts D D", that of the bolts D being lateral, so as to draw said pieces against the web of the rail, and that of the bolts Dbeing vertical, so as to draw thepiece downward and against the base of the rail. By this provision there is a two-part adjustment of the splice-pieces,andshould the latter becomeloose, either at their ends or bases, they may be tightened at either place, and thus be held firmly in position, preventing rattling of the parts. The base B is slotted to receive the bolts D, whereby the cheek-pieces C may be moved inward or outward,aecording to requirements, while adjusting the same.

F represents a rail or plate, which is extended upward from the cheek G,(see Fig. 2,) and bears against the under side of the head of the rail, thus serving as a guard, chair, support, or stiffener, especially to joints of rails laid on curves.

If desired, one of the splice-pieces may be formed integral with the adjacent eheek,O, as in Fig. 3, and it is evident that the other splicepiece may be formed integral with the check 0, the latter, however, being separate from the base of the chair.

. In Fig. 2 tl1c end of the base B, adjacent to the cheek C, has an npwardl y projecting flange, B, which serves to keep the said check more securely in position.

I am aware that it is not new to employ a wedge-piece to keep a bolted fish-plate in position; neither is it new to use fastening devices to secure said wedge-piece in its place, and such I do notbroadly claim.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. A chair for thejoint ofrailroadrails,ha"- ing the slotted base A,a splice-piece with parts E E, the part E being in contact with the base, the bolt D which passes through the part E and the web of the rail, and the cheek resting on the part E and secured by the bolt D to thebase, substantially as described.

2. A chair for thejoi nt of railroad-rails,hav-

ng a base and cheek-pieces onopposite sides, ing through the parts E of said splice pieces ingularsplice-pieces,and vertical and horizonand the web of the rail, substantially as de a1 bolts, said splice-pieces being formed of scribed.
